Yuwell YN-03 Nasal Mask for CPAP / APAP / BIPAP This mask is ideal for nose breathers who do not rely on their mouth to breathe at night time. Alternatively, you can also use a chin strap to ensure nose-breathing throughout the night. The new Yuwell Breathwear YN-03 nasal mask delivers extreme comfort with its off-the-forehead design and the anatomically designed mask means pressure is evenly distributed around the nose area. The mask is designed so you are able to lay on your sides without the mask making contact with the pillow. This provides more comfort, a better fit, an improved seal and less time adjusting your mask throughout the night. Features: Anatomically corrected suspension silicone for a superior seal. Adaptive silicone moulding for different facial structures Quiet vent hole. Very quiet operation. Quick-release connector Soft and light headgear Super lightweight at only 64g Therapy pressure: supports 4-30 cmH2O Tube connection: Standard 22mm Flow resistance at 50L/Min:
